Injury updates: Pitta, McPhee on the mend

After missing the previous three games with right knee and thigh injuries, starting left defensive end Pernell McPhee practiced for the second consecutive day on a limited basis.

McPhee underwent a pair of arthroscopic knee surgeries prior to training camp, which has limited his production to a half-sack after recording six sacks as a rookie last season.

"I'm getting better, I'm getting my feet back under me," McPhee said. "I'm doing all the easy stuff on the field, but coach [John] Harbaugh will make the decision on whether I'm out there Sunday."

Tight end Dennis Pitta will soon take baseline neurological test to determine if he's medically cleared for contact, but said he's no longer dealing with concussion symptoms.

"I've taken a few big hits these last few weeks, but I feel good," Pitta said. "We'll see where we're at, but I feel pretty good."

Reserve cornerback Chris Johnson didn't practice again due to a strained hamstring, but return specialist Jacoby Jones was upgraded to limited participation after being held out Wednesday with an ankle injury.
